Comparative Study
Arrival by ambulance is associated with acute stroke intervention in young adults.
Timely intervention in young stroke patients minimizes long term disability. We hypothesized that arrival to the emergency department by ambulance would be associated with increased rate of stroke intervention with intravenous t-PA or intra arterial procedures. ⋯ Young adults with stroke symptoms were more likely to receive acute stroke intervention if they arrived by ambulance. Larger multi-center studies should address whether Primary Stroke Centers are more likely to provide either IV thrombolysis or interventional therapies in young patients with acute ischemic stroke.

Ischemic lesion growth may be a surrogate marker of clinical outcome, but no such interrelationship after thrombolysis has yet been determined. We evaluated the association between early infarct growth on diffusion-weighted imaging (DWI) and long-term clinical outcome after thrombolysis. ⋯ Early DWI lesion growth is an independent predictor of poor outcome after thrombolysis and may serve a potential surrogate marker of clinical outcome in acute stroke trials.

Recent studies suggest that the Montreal Cognitive Assessment (MoCA) is more sensitive to stroke-associated cognitive dysfunction than the Mini-Mental State Examination (MMSE), but little is known about how these screening measures relate to neurocognitive test performance or real-world functioning in patients with good recovery after aneurysmal subarachnoid hemorrhage (aSAH). The aim of the present study was to determine how MoCA and MMSE scores relate to neurocognitive impairment and return to work after aSAH. ⋯ Compared to the MMSE, the MoCA is more sensitive to aSAH-associated cognitive impairment. Certain MoCA subtests are also sensitive to functional difficulties after aSAH such as return to work. These findings support the utility of the MoCA as a brief bedside assessment of cognitive and real-world outcome in aSAH survivors.

Cardiac arrest is a leading cause of death that affects more than a million individuals worldwide every year. Despite the recent advancement in the field of cardiac arrest and resuscitation, the management and prognosis of post-cardiac arrest brain injury remain suboptimal. ⋯ Considering that a potentially broad therapeutic window for neuroprotective drug therapy is offered in most successfully resuscitated patient after cardiac arrest, the need for further research is imperative. The aim of this article is to present the major pathophysiological disturbances leading to post-cardiac arrest brain injury, as well as to review the available pharmacological therapies.

Dementia is associated with insulin resistance in patients with Parkinson's disease.
Parkinson's disease is a neurodegenerative disorder involving the basal ganglia. Type-2 Diabetes Mellitus is an important risk factor for Alzheimer disease and vascular dementia. However, the association between Parkinson's disease and Diabetes Mellitus is controversial. ⋯ Our study suggests that PD patients with dementia are two times more likely to have insulin resistance than patients with PD.
